Is HTTPS slower than HTTP?

Not meaningfully anymore. Modern TLS and HTTP/2 make secure connections fast, and the security benefits far outweigh the negligible overhead.

Yes. Search engines treat it as a ranking signal and browsers flag insecure pages, so HTTPS improves both rankings and user trust.

How do I move from HTTP to HTTPS?

Install a TLS certificate, 301-redirect all HTTP URLs to their HTTPS versions, update internal links, and enable HSTS to enforce secure connections.

HTTP vs HTTPS

HTTP and HTTPS are the protocols browsers use to fetch web pages, and the single letter difference is huge. HTTP sends data in plain text, so anyone between the user and the server can read or tamper with it. HTTPS wraps the same traffic in TLS encryption, protecting confidentiality and integrity and verifying the server's identity.

HTTPS is no longer optional. Browsers mark plain HTTP as "Not Secure," search engines favor secure pages, and modern features require it. The performance gap that once justified HTTP has largely vanished thanks to modern TLS and HTTP/2.

At a glance

Aspect	HTTP	HTTPS
Encryption	None — plain text	TLS-encrypted
Data safety	Readable by intermediaries	Confidential and tamper-evident
Identity	Not verified	Verified via certificate
Browser label	"Not Secure"	Padlock / secure
SEO & features	Penalized, limited features	Preferred, unlocks modern APIs

When to use HTTP

Practically never for public sites in production.
Local development or isolated internal testing only.
Legacy systems you're actively migrating off.

When to use HTTPS

Any public website or web app.
Anywhere you collect data, logins, or payments.
You want SEO, trust, and modern browser features.

Verdict

Use HTTPS everywhere — there's essentially no case for plain HTTP on the public web today. Free certificates from Let's Encrypt removed the cost barrier, and HTTP/2 removed the speed excuse. Serving HTTP exposes users to eavesdropping and tampering, triggers browser warnings, and hurts SEO. Redirect all HTTP traffic to HTTPS with a 301 and enable HSTS to enforce it.
